_Sources

The _Sources table describes the data sources of the dimensions and cubes to be loaded. The source are identified with a number in the other tables. The details are stored here.

The other metadata tables contain a column called SourceId. The ID read from the other tables is used to find the correct row in the _Sources table. If there is no entry, the appropriate table or view in the same database as the metadata tables is used. When looking up the source in the _Sources table, the source type and the connection parameters are read. Depending on the type, this can be either a direct connection string or the ID used to retrieve a connection string from a global data source.

This table describes _Sources:
